Bess [88]

Answer:

A. Renin levels increase with poor kidney perfusion

D. Nephrotoxic drugs are a cause of intrarenal failure.

Explanation:

Renin is produced in the kidney for angiotensin aldosterone hormonal system and it is helpful in maintaining the blood pressure and other metabolic activities. However when the renin level is high then it means the kidney has a perfusion issue .

Nephrons are kidney cells. When a drug which is toxic to them gets into the body system then it affects the kidney and may cause kidney failure.

svet-max [94.6K]

INCOMPLETE DOMINANCE INHERITANCE:

<span>5.  In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.  These genes, however, show incomplete dominance.  The heterozygous (BB') condition results in blue plumage.  List the genotypic and phenotypic ratios expected from the following crosses:  a) black x blue  b) blue x blue  c) blue x white</span>

<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r).  Heterozygotes have petals, which are neither red nor white, but pink.  a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants?  What fraction of the gametes produced by the F1 plants would be expected to bear the R allele?  b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>
